Resistive Touch

Do we have to install the cab file for Resistive touch to work . we tried with out installing the cab file still the touch is working.
Can you tell us is it mandatory to install the cab file.
We are using 4.3 inch TFT.

Dear @zecons

The resistive touch screen is supported by default on all our modules and all WinCe versions. There is no need to install any additional .cab file for this.

So the must be there for a rather special usecase. Can you point me to the link where you found that cab file, so I can find out what the purpose of this installer was?
